VAPGREZER FOR HYDROCA'RBON-LAM PS.

SPECXFIGATION forming part of Letters Patent No. 630,549, dated August 8, 1:899.

Application filed April 17, 1899.

To @ZZ whom jt may concern.-

Be it known that JACOB MOSKOWITZ, a

citizen ot' the'Uiited States, residing at Chicago, in the county of Cook and State of lllinois, have invented a new and useful Improvement in Vaporizers for Hydrocarbon- Lamps, of which the following is a specification. y g

My invention relates to improvements in the construction of 'the vaporizing tubes or chambers employed in connection. with lamps or ixtu res of the class wherein a volatile hydrocarbon oil from a suitable reservoir is fed through and gasiied in a chamber. which is heated from the dame of the lamp and thence discharged to mix with air and enter a mixing-tube which conducts the mixture to the burner. The vaporizing-chamber and mixing-tube together form a construction of the Bumsen-burner type, which in practice reqnires that the outlet from the vaporizingchamber or generator shall be comparatively small to give desired force to the current of escaping gas, andin the constructions of vaporizing-chambers or generators hitherto employed great difficulty has been experienced on account of the frequent clogging of this outlet by particles of carbon or other material carried with the gas. My object is to provide a vaporizing-chamber or gas-generating device of improved con-4 struction in which the danger of clogging will be obviated; and to this end my invention consists in the general as well as details of construction and combinations of parts, all as hereinafter set forth and claimed.

Referring to the drawings, Figure l isa gasge'nerating gas-lamp provided with my improvements; Fig. 2, an enlarged and broken section vtaken on the irregular line 2 of Fig. l Fig. 3, a still further enlarged section taken on line of Fig. l; Fig. 4, a View illustrating the construction of one form of strainer which l employ, and Fig. 5 astrainer of alternative construction.

A is a ixture or lampcarrying support formed with a reservoir B, oil-conducting pipes t, mixing-tube C, Vand burner C', the parts s and s being bracing rods or 'tubes plugged at the ends.

The particular shape or construction of the parts named forms no part of my present inserial no. 713,354. (No man.)

vention vand maybe of any suitable construction.

D is my improved gis-generating or vaporiz/.ing device, which ,as shown,`compriscs tubes r fr', which may extend parallel with cach.

other and provided at opposite ends with caps 'r2 r3, respectively, common to both and forming chambers. The cap r2 is screwed upon the end of ythe tube t', so that the generator extends in a horizontal plane in the direction,

of the mouthpiece q of the tube C. Screwed upon the cap rs isl a dischargecap 7A, having a minute discharge-opening v5 in direct line with the inlet-opening q of the mouthpiece q. l prefer to employ two tubes T r', extending side by side in the horizontal plane and in vertical plane with the burner C. However, more than two such tubes may be employed, it' desired, and so far as certain details of my invention are concerned asinglc tube may be employed.

In operation hydrocarbon oil from the reservoir B passes downward through the supply-pipes t t to the chamber r2 and the chamber formed by the tubes 'r fr. The latter are heated from the burner C' to vaporize the oil and cause it to discharge under pressure to the chambers r3 r? and escapenthrough the minute opening 1'5 to the mouthpiece q. On

the principle of the Bunsen burner a suitable controlied. As the oil is vaporized any solid particles of carbon or foreign substances would be carried by the gas to the outlet ri to clog the same unless straining means, such as it is the object of my inventin toprovide, are placed between the inletlcha'mber r2 and outlet 1'5. In the tube fr i show a strainer E, consisting of loosely-packed asbestos or other refractory or incombustible material p,wrapped or confined in a foraminous casing p'. The casing may be formed of a strip ofrefractory metal wire-gauze wound ,spirally over the looselypacked Filler p, and the tube thus formed is provided at its end adjacent to the chamber vr3 with a shield or cartridge p2. The

tubo or casing p may be constructed in any other suitable manner and should preferably be of a diameter somewhat less than the inner surface of the tube v' to be out ot' contact therewith throughout the greater part oi its extent at least. Oil entering the tube rfrom the chamber fr2 is absorbed by the porous filler p, and the latter becomes more or less saturated. Under the heat applied to the tube the oil is vaporized and escz'tpes from the iller through the porous casing into the tube 'i' and passes around or through the shield or cap p2 to the chamber r3. All solid particles of carbon or other material are retained by the filler and prevented from reaching the cha1i1l.ie1o",\vlxile the cap p2 prevents any particles of the filler material -1`ron1 being carried through it. In the construction shown in the tube `r a series of shields or cartridges p2 are provided,` the same being filled with loosely-packed straining material, such as asbestos liber or other comparativelyincombustiblcsubstance. The cartridges may be of conical form, as shown, and present obstructions to the escape of the filler in the direction of the chamber r3. 'lhe oil entering from the chamber r2 is absorbed by the iller material, and as it is vaporized or gasied under the heat it escapes through the porous material of the cartridges, which may be of wire-gauze, and moves to the chamber r3. The 'lillcrji and its casing, whether in one length, as shown in thc tube Ir, or in the form of caps or cartridges, as shown in thc tube yr', will strain the gas, so that it will be practically free from solid particlas when it reaches the minute outlet yf5. rIhus there can be no clogging of the latter. In the event that the Iiller material or cartridges become so impregnated with solid particles as to prevent suiciently tree passage of the hydrocarbon they may be removed and cleaned or provided with fresh filling material. The abstraction and rcinsertion of the straincrs may be quickly and easily accom plis-hed.

'.lhere is a material advantage in providing a plurality of--that is to say, two or moretubes, for the reason that they increase the capacity ot the vaporiziiig-chamber as well as the surface exposed to the burner; also, because in the event that one channel should become clogged the other or others will still remain open for the passage of the hydrocarbon.

There is an advantage in providing more than one outlet through the cap r, as indicated by dotted lines in Fig. 3, and owing to my improved straining means these openings may be very minute without danger of clogging. A series of such outlets diminishes the noise of the escaping gas and prod nces a more steady` llame at the burner.

While I prefer to construct my improvements as shown and described, they may be variously modified in the matter of details without departing from the spirit of my invention as defined by the claims.

What I claim new, and desire to secure by lLetters Patent, is

l. In combination with a hydrocarbonburner, a hydrocarbon-oil-supply conduit, a vaporizing-chamber above the burner, to be heated thereby, and interposed in the path of the hydrocarbon from the supply-conduit to the burner, and a strainer in said chamber through which the hydrocarbon must pass, comprising a series of porous cartridges having an oil-absorbing iillcr all of refractory material, substantially as' and forthcpurpose set forth.

2. In combination with a hydrocarbonburner, a hydrocarbon-oil-supply conduit, a vaporizing-chamber consisting of a plurality ot tubes forming separate passages extending over the burner, to be heated thereby, and interposed in the path of the hydrocarbon from the supply-conduit to the burner, and strainers in said tubes through which the hydrocarbon must pass, comprising refractory oil-absorbing material provided at its discharge end with a refractory foraminous shield, substantially as and for the purpose set forth.
